Hybrid system life expectancy (from case mileage)
Mileage at the time the HV battery, inverter and similar parts were the cause or were replaced. This is not an average lifespan but the median and range (10th to 90th percentile) of the mileage at replacement.
| Part | Japanese cases | Overseas cases |
|---|---|---|
| Brake booster | Median 125,000 km (65,000 to 145,000 km, 3 cases) | Too few cases with mileage |
Cases without mileage are excluded. Results vary widely with usage (repeated short trips vs. long highway runs) and climate.
